Where Is the Best Place to Go to Buy Electronic Components Online?

As Barney says, Digikey is a good place. Mouser is another good place. All Electronics Corp. might be another possibility. And again as Barney says, buying 1 resistor might not be possible from on-line or mail order. You are talking about something that costs about 2 cents. If you live in a larger city, there must be an electronics supply store locally. Something like Norvac Electronics or other parts house. Many sell to the general public

1. Which is more powerful either fully equipped printed circuit or microchip that is not able to re-code?

For this question I have no answer as it is fully unclear to me what is your problem.Nearly each approach to solve an electronic issue ends up in a printed board with electronic components attached to it. This can be active components, passive components and sub assemblies. Active components are transistors diodes and also micro-controllers and much more.. Passive components are resistor,s capacitors and some sensors. Modules can be Arduino Nano boards, power supplies and other functional boards which for instance you can by like a LiPo charger module or a MP3 Player. So I have a problem to judge which is more "powerful"??? and the expression "recode" - I have never come across...My recommendation: before placing a question to Quora start thinking about what you want to achieve and whether your question is understandable to the person which is requested to answer...

2. Software for workshop - electronic components stock management

I am not trying to be silly, sarcastic, snarky, stupid or any other s-word. I want this answer as much as you do. Do not select this answer. But I saw what happened when the Navy tried to go paperless in their supply lines. It was a bureaucratic nightmare that required retraining to participate in, and it somehow managed to generate even more paper waste. I prefer classic methods - catalogs, log book, and index cards. The catalog identifies where the part is in the log book, and the log book identifies which index card is applicable. Getting a new part means adding the next index card and the next log book entry serially. The catalog gets updated with the log book volume and entry number and is actually categorized. The index card itself maintains the location and quantity data for the part. If you need a part, you retrieve the card, go to the place, get the stuff, and take it to the clerk. Clerk updates the card, decides if it needs to be ordered, and puts the card back. Expensive stuff stays under lock and key with the clerk or his boss. You can go to the trouble of using fire safe-boxes for all the cards, but in reality all that you have to keep safe is the logbook and the catalog; in the event of a big casualty, you will be auditing inventory anyway. I dare not say this is what you want. I say this is cheap, easily trained on, multiple access, and has 100% uptime once implemented. Project files can easily directly reference the associated index cards, as can ongoing and periodic maintenance files. Technicians immediately know exactly what they need and exactly where to find it. Data entry still sucks - once. The serialized index cards for 1000 different components should be about 7 inches thick.If you want an audit, flip through the stack, grab a card and go look. If you want to use multiple catalogs, fine - just keep adding to the serialized log-book and index cards as you add parts to inventory. Retire a part? Throw away the card and line it out of the log book

3. which material(s) is used in production of electronic components such as transistor, diode, logic gate & ics ?

Silica or silicon was and is a major component of that. Certain 'new' metals have caught the fancy of corporations like Intel in a new way of configuring data transfer bytes. Copper and other metals are used. Silk Screening is a way to 'print' circuit boards. Plastics and Fibers are also used. They are not broadcasting it yet.

4. What Are the Functions of a Circuit Board? - Engineering Technical -PCBway

circuit boards or printed circuit boards (PCB) are thin plates containing electronic components mostly found in electrical and communications devices. The plate allows circuit components to transfer information and signals between each other as well as information to external devices. Circuit boards can be found in computers, televisions, cell phones, and other telecommunications devices. There are also different types for circuit boards, from traditional computer motherboards to tiny flexible boards used in mobile phones and PDAs. Function PCBs are made of different parts and resins with circuitry on the surface to connect parts to one another. A PCB will usually have components for memory chips, processors, input/output devices, and then electrical components like resistors and capacitors. With the progression of technology circuit boards have become smaller while accommodating more components. Capacitors are now embedded into circuit boards which increase circuit performance and allow circuits to become smaller. Motherboard Motherboards can be found in computers and laptops. They are the large circuit boards with circuitry connections for a CPU or central processing unit, memory like RAM, input/output devices and USB connections, and a graphics processing unit. Motherboards allow all the electronic devices to communicate with one another. Daughter Board Daughter boards, or expansion boards, in desktop computers have generally been replaced by PCI type devices, but some examples of daughter boards include sound cards and modem cards. A daughter board is a device that extends the capabilities of the motherboard by providing an external hardware feature, like graphics, networking, or sound. Uses Circuit boards can be found in many electronic devices and are integral to the electronics industry. They can be used to connect LCD monitors to computers, disk drives and hard disk drives, and read and write drives like CD-ROM and DVD drives. In telecommunications systems, circuit boards are attached to metal plates to create a metal-backed assembly. Flexible Circuit Boards Flexible circuit boards are made of a laminated material that has insulation to resist heat, electrical properties, metal foil, and adhesive. Usually, conductive bumps allow conductivity between the flexible circuit board and another circuit board by pressing the bumps to pads with pressure. This creates electric flow between the systems. Flexible circuit boards are known for their lightness, thinness, flexibility, and convenience in size.
